INTEGRATED CIRCUITS 74F651A/74F652A Transceivers/registers Product specification Replaces datasheet 74F651/74F652/74F651A/74F652A of 1990 Oct 23 1999 Jun 23 IC15 Data Handbook Philips Semiconductors Philips Semiconductors Product specification Transceivers/registers 74F651A Octal transceiver/register, inverting (3-State) 74F652A Octal transceiver/register, non-inverting (3-State) FEATURES 74F651A/74F652A Combines 74F245 and two 74F374 type functions in one chip High impedance base inputs for reduced loading (70µA in high and low states) DESCRIPTION The 74F651A and 74F652A transceivers/registers consist of bus transceiver circuits with 3–State outputs, D–type flip–flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes high. Output enable (OEAB, OEBA) and select (SAB, SBA) pins are provided for bus management. Independent registers for A and B buses Multiplexed real-time and stored data Choice of non-inverting and inverting data paths 3-State outputs Industrial temperature range available (–40°C to +85°C) for 74F652A TYPE 74F651/74F652 74F651A/74F652A TYPICAL fmax 110MHz 175MHz TYPICAL SUPPLY CURRENT( TOTAL) 140mA 110mA ORDERING INFORMATION ORDER CODE DESCRIPTION COMMERCIAL RANGE VCC = 5V ±10%, Tamb = 0°C to +70°C N74F651AN, N74F652AN N74F651AD, N74F652AD INDUSTRIAL RANGE VCC = 5V ±10%, ...
